CVE-2025-67172 is an authenticated remote code execution (RCE) vulnerability discovered in RiteCMS version 3.1.0. The flaw resides in the parse_special_tags() function, which improperly handles input, leading to command injection vulnerabilities classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command) and CWE-94 (Improper Control of Generation of Code). Exploitation requires an attacker to have high-level privileges (PR:H) within the system, meaning they must already be authenticated with elevated rights. The vulnerability allows an attacker to execute arbitrary code remotely without requiring user interaction (UI:N). The CVSS v3.1 base score is 7.2, indicating a high severity level, with impacts on confidentiality, integrity, and availability (all rated high). No patches or fixes have been published yet, and no known exploits are currently in the wild. The vulnerability's network attack vector (AV:N) means it can be exploited remotely, increasing its risk profile. The lack of user interaction and the requirement for high privileges suggest that the threat is primarily from insiders or attackers who have already compromised lower-level credentials and escalated privileges. The vulnerability could be leveraged to take full control of affected RiteCMS installations, potentially leading to data breaches, defacement, or disruption of services.

For European organizations, the impact of CVE-2025-67172 can be significant, especially for those relying on RiteCMS for content management and web presence. Successful exploitation could lead to unauthorized access to sensitive data, website defacement, or complete system compromise, affecting business continuity and reputation. Given the high privileges required, the threat is more likely to come from malicious insiders or attackers who have already breached perimeter defenses. Organizations in sectors such as government, finance, healthcare, and critical infrastructure that use RiteCMS are at heightened risk. The vulnerability could also be leveraged as a pivot point for lateral movement within networks, increasing the scope of compromise. The absence of a patch means organizations must rely on compensating controls, increasing operational overhead. Additionally, the remote nature of the exploit vector means attackers can launch attacks from anywhere, potentially increasing the attack surface for European entities.

1. Immediately restrict administrative and high-privilege access to RiteCMS to trusted personnel only, implementing strict access controls and multi-factor authentication. 2. Monitor logs and system activity for unusual behavior indicative of privilege escalation or code execution attempts, focusing on the parse_special_tags() function or related CMS components. 3. Employ network segmentation to isolate RiteCMS servers from critical internal networks, limiting lateral movement opportunities. 4. Use web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting the vulnerable function. 5. Regularly audit user accounts and permissions within RiteCMS to ensure no unauthorized privilege escalations have occurred. 6. Prepare incident response plans specific to CMS compromise scenarios, including backup and recovery strategies. 7. Engage with RiteCMS vendors or community for updates and patches, and plan for rapid deployment once available. 8. Consider temporary disabling or limiting features related to parse_special_tags() if feasible, to reduce attack surface until a patch is released.
